CentOSでHyperledgerFabricのサンプルシステム「fabcar」を動かすまでのコマンド

Last updated at Posted at 2019-10-25

はじめに

ブロックチェーン基盤の一つHyperledgerFabricのサンプルシステムfabcarをCentOS上で動かしてみた。
サンプルで提供されるSDKを動かすまでのコマンドをまとめたので記録しておく。

CentOSのバージョン確認

CentOSコンソール
$ cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)

まずcentosを日本語化

参考

CentOSコンソール
$ sudo yum -y install ibus-kkc vlgothic-*
$ vi ~/.bash_profile

.bash_profileを編集する。

.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

# 追加ここから
LANG=ja_JP.UTF-8
 export LANG
# 追加ここまで
CentOSコンソール
$ source ~/.bash_profile
$ a
-bash: a: コマンドが見つかりません     ←日本語になってることを確認

HyperledgerFabricの前提ソフトインストール

$ groups
centos adm wheel systemd-journal

$ sudo usermod -aG docker centos

#再度ログイン

$ groups
centos adm wheel systemd-journal docker

dockerコマンドをsudoを書かなくてもようにする
CentOSコンソール
sudo groupadd docker
sudo usermod -aG docker centos

docker起動

$ echo 'export GOPATH=$HOME/go' >> ~/.bash_profile
$ echo 'export PATH=$PATH:$GOPATH/bin' >> ~/.bash_profile
$ source ~/.bash_profile

$ go version
go version go1.11.10 linux/amd64

ここまでで、fabcarシステムを構築、invoke,queryのSDK実行が完了。

ちなみにqueryの結果を整形すると以下

  • 1レコードはこんな感じ
    {
     "Key":"CAR0",
     "Record": {
       "colour":"blue",
       "make":"Toyota",
       "model":"Prius",
       "owner":"Tomoko"
     }
    }

  • 表にまとめるとこんな感じ

Key colour make model owner
CAR0 blue Toyota Prius Tomoko
CAR1 red Ford Mustang Brad
CAR12 Black Honda Accord Tom
CAR2 green Hyundai Tucson Jin Soo
CAR3 yellow Volkswagen Passat Max
CAR4 black Tesla S Adriana
CAR5 purple Peugeot 205 Michel
CAR6 white Chery S22L Aarav
CAR7 violet Fiat Punto Pari
CAR8 indigo Tata Nano Valeria
CAR9 brown Holden Barina Shotaro

※CAR12がinvokeで追加された車
